Gotcha. I used the tremec app on my iphone and it helped make sense of the angles. You literally use the level in the phone to measure 3 angles and it gives you your totals. Pretty neat setup.
I used a free app called "iLevel" which works nicely, and the graphics (changeable) are easy to see even without my reading glasses on.
